Rain and Flooding
Rain is a type of precipitation which is readily absorbed by the ground. However, flooding might occur if there is a downpour or heavy rain. Flooding can result in damage to property, illness and even death.
Asked in Rain and Flooding, Grasslands
Seasonal grassland are found?
Seasonal grasslands can be found in places where there are drastic changes in the weather from one season to the next. For example, it could be found in the tundra and parts of the northern steppes, where the grassland turns to an icy desert in winter. It can also be found in North-Central Africa south of the Sahara Desert, in a region called the Sahel, where a deserted landscape could turn into a grassland during the rainy season. ...

How many inches of snow would one inch of rain produce?
The ratio of snow to water can vary a great deal depending on the vertical profiles of temperature and moisture, and how they change during a storm. Typically 1 inch of rain is equal to 1 foot of snow, a 12-1 ratio. Depending on the temperature and moisture profiles of the snow growth region of the atmosphere and the origin area of the storm system, that ratio can go higher, say 20-1, which would be 20 inches, or lower, say 6-1...

Why does river straightening reduce flood risk?
Straightening of river reduces floods in the immediate area because it allows the water to go straight instead of having to turn through curves. A natural meandering river has a curvy or sinusoidal shape to its path. A straight river would travel only a kilometer per kilometer of valley floor. Water associated with a curvy river will have to follow the natural sinusoidal curves and will travel considerably more distance per kilometer of valley floor. Also, water in a natural river will...

What role does temperature play in the water cycle?
If the temperature is on the higher side, water from the rivers, oceans evaporate at a faster pace. The more the heat in the summer, the more the possibility of excessive rain during rainy season. In this way, temperature plays a crucial role in the water cycle. ...

How do rivers contribute to flooding?
Floods are natural events. They mainly happen when the river catchments, (that is the area of land that feeds water into the river and the streams that flow into the main river) Which receives greater than usual amounts of water Here is an example through rainfall or melting snow. The river cannot cope and this extra water causes the level of the water in the river to rise and a flood to take place. This flooding may take place at any point along...
Which are the most vulnerable homes during floods?
MOST VULNERABLE HOMES 1. Buildings, which are constructed with earth-based materials or using stone and brick in mud mortar are highly vulnerable to damage in heavy rains and/or floods. 2. The huts made from biomass materials like bamboo, leaves, thatch or light construction using metal sheets are easily destroyed in floods and washed away. 3. The occupation of areas within the flood plain of rivers has increased the vulnerability, especially in areas of high population concentration. Flood plains attract poor people because of inexpensive land values. ...
Is red sky in the morning sailors take warning red sky at night sailors delight is based on a myth or a fact?
Both, but more on fact. Since the sun comes up in the east, a red sky in the morning often means there is adverse weather developing, whereas if there's red sky at dusk, then the inclement weather has passed and there will be a nice day the following day. _______________________________ It's a simplification based on the fact that most weather systems move from west to east. It's not a "fact", but it is based on probable events in the next 12 to 24...
Asked in Rain and Flooding
What effects do floods have on buildings?
EFFECT ON BUILDINGS The damage to buildings due to floods are as follows: 1) Houses are washed away due to the impact of the water under high stream velocity. The houses are commonly destroyed or dislocated so severely that their reconstruction is not feasible. 2) Houses constructed out of light weight materials like wood float when they are not anchored properly. 3) Damage caused by inundation of house. The house may remain intact on its foundation, but damage to materials may be severe. Repair is often feasible...
Asked in Mining, Rain and Flooding
What happens to ore after it's been mined?
Extracted Ore is crushed smelted, a chemical process usually requiring huge quantities of heat at very high temperature, to extract the metal from the mineral that was the ore. Eventually each specific ore deposit is exhausted and the mine falls into disuse. ...
